TIDA-00078, Direct Down-Conversion System with I/Q Correction

Descripción

• TIDA-00078, Direct Down-Conversion System with I/Q Correction. The I/Q Correction block implemented in the Field Programmable Gate Array (FPGA) of the TSW6011EVM helps users to adopt a direct down conversion receiver architecture in a wireless system. The I/Q correction block consists of a single-tap blind algorithm, which corrects the frequency-independent I/Q imbalance in a complex zero-IF receiver system. Along with the I/Q correction block, the FPGA includes a digital gain block, a digital power-measurement block, x2 of interpolation block, an I/Q offset correction block, and a quadrature mixing block
